A liquid-crystalline medium which comprises at least one compound selected from the group of compounds of the formulae IA to IH, in which

Liquid-crystalline medium

The present invention relates to a liquid-crystalline medium (LC medium), to the use thereof for electro-optical purposes, and to LC displays containing this medium.

Liquid-crystal medium

The invention relates to a liquid-crystalline medium and to the use thereof for an active-matrix display, in particular based on the VA, PSA, PS-VA, PM-VA, SS-VA, PALC, IPS, PS-IPS, FFS or PS-FFS effect.

A liquid-crystalline medium having a nematic phase containing one or more compounds of formula D the use thereof in an electro-optical display, particularly in an active-matrix display based on the IPS or FFS effect, displays of this type which contain a liquid-crystalline medium of this type and the use of the compounds of formula D for improvement of the contrast and/or response times of a liquid-crystalline medium which contain one or more additional mesogenic compounds, as well as certain compounds of formula D.

Liquid-crystalline medium and liquid-crystal display comprising the same and compounds

The invention relates to a liquid-crystalline medium which comprises at least one compound of the formula I, wherein the radicals R, L, L, n and A are as defined herein, and to the use thereof for an active-matrix display, in particular based on the VA, PSA, PS-VA, PA-VA, PALC, FFS, PS-FFS, IPS or PS-IPS effect.
